I work with engineers and technical managers with 25+ years of experience, building and maintaining serious business software 'you could run a country with' - people here build react web apps or do scientific research, or work for a SaaS provider - completely different view than building highly complex, regulated, mission critical software that supposed to run for decades and be supported at this level.
I use DriveSync on Android to sync selected Gdrive folder to my phone.
It works.
